My ovulation day was to be on or close to friday 10-26-07. My BF and I were together on wed 10-24-07 and 10-25-07. My period is not expected till 11-9-07. By tue 10-30-07 I started to feel period like cramps and lower back pain. I have never noticed feeling this way before any of my other periods. Could I be pregnant? How soon should I test?
